Ni ubuhe bwoko butandukanye bwa PCB?
Ibice bya PCB bibaho muburyo butandukanye bwa porogaramu zitandukanye. Guhitamo inyubako ikwiye kubicuruzwa bizakenera injeniyeri gusuzuma imikoreshereze igenewe igikoresho, ibipimo byayo hamwe nimbaraga zayo. Ongera usuzume ibi bikurikira kugirango wumve ubwoko bwibibaho byacapwe byanditse kandi nubwoko bukwiranye nibikorwa byawe:
PCBs uruhande rumwe: guhimba PCB bikubiyemo gukora ikibaho cyumuzunguruko kiva murwego rumwe rwa substrate hamwe nicyuma cyoroshye. Ibigize byose bigurishwa kuruhande rumwe.
PCBs zibiri: Ubwoko bwa PCB aho impapuro ziyobora zikoreshwa kumpande zombi za substrate.
Imyobo irashobora gucukurwa hagati yikibaho cyumuzunguruko kugirango yemere guhuza gukora kumpande zombi.
PCBs nyinshi: Nibura byibuze PCBs eshatu zibiri zegeranye hejuru yizindi hamwe nuburyo bwinshi bwo kubika kugirango ugabanye ubushyuhe. Ibikoresho bidasanzwe bifata neza bikomeza urukurikirane rwa PCB hamwe.
PCBs ihindagurika: Ikibaho cyumuzingo cyacapwe cyerekana substrate yoroheje kugirango ifashe injeniyeri guhuza imiterere yibicuruzwa. Tekinoroji irashobora kubaho muburyo bwuruhande rumwe, impande ebyiri cyangwa inyubako nyinshi.
PCBs Rigid: Ifite akamaro kubicuruzwa byabaguzi bigumana imiterere imwe mubuzima bwabo bwose. PCB zikomeye zakozwe hifashishijwe insimburangingo irwanya kugoreka.
Rigid-flex PCBs: Icapa ryumuzingo wacapishijwe ukoresheje ibikoresho bikomeye kandi byoroshye. Iboneza ryemerera abategura ibicuruzwa kubika umwanya, nkuburyo bukomeye kandi bworoshye bwo guhuza bushobora gushirwa kumurongo umwe wumuzunguruko.
PCBs ishyigikiwe na Aluminium: Ubwoko bwa PCB busimbuza substrate ya aluminium aho fiberglass yaba. Yashizweho kugirango ikoreshwe hamwe nimbaraga za PCB za elegitoronike nkamatara ya LED.
PCBs nyinshi cyane: Ikibaho cyumuzunguruko cyakozwe kugirango cyohereze ibimenyetso bikomeye nka 2 GHz.
PCBs Yakozwe Niki?
Gahunda yo guhimba PCB isa itandukanye ukurikije intego igenewe igice nuburyo imbaraga zikenewe kugirango ibikoresho bya elegitoronike bikore. Mbere yo guhitamo ibikoresho byiteraniro ryumuzunguruko, nibyiza ko umenyera ibice bine byingenzi bigize PCB:
Substrate: Imiterere yimiterere yumuzunguruko - ibice byose bifatanye kuri ubu buso.
Laminates: Ibikoresho bifata ibice byose bya PCB hamwe.
Maskeri ya Solder: Yicaye hejuru yumuringa wumuringa hagamijwe kwigunga kandi ikingira imiyoboro yibidukikije.
Silkscreen: Ihambire kubagurisha mask kugirango ibice bishoboke.
Igishushanyo ni iki?
Igishushanyo, cyangwa igishushanyo, ni ishusho yibintu bya sisitemu ukoresheje ibimenyetso bifatika, bishushanyije aho gushushanya bifatika.
Nibihe bitangwa kuri serivise ya PCB?
Kumurongo wa serivisi ya PCB Layout, amakuru akurikira azatangwa muri dosiye isohoka:
Datasets yuzuye ya Gerber harimo dosiye ya drill (Ibice byumuzunguruko, Mask layer, Silk layer, Outline, Drill layers, Paste layers)
Tora & Shyira amakuru
Umushinga wanyuma wibikoresho bya dosiye
Umushinga Netlist na dosiye ya PDF
Ni ubuhe bwoko bw'ibikoresho bukoreshwa mugukora PCB zikomeye?
Ibikoresho bya FR4
Ibikoresho byihuta byerekana ibikoresho
Umuvuduko mwinshi FR4 substrate hamwe na DF 1Ghz.
Umuvuduko mwinshi FR4 substrate hamwe na Df 10Ghz
Ibikoresho bike bya Df ceramic, imikorere kuri 10Ghz
Ibikoresho bya PTFE cyangwa ibikoresho bya PTFE bishimangiye
Ubushyuhe bwo hejuru PTFE ibikoresho
Ni ubuhe bwoko bwo guhimba bukoreshwa mugukora PCB zikomeye?
Hariho uburyo bwinshi bwo guhimba bukoreshwa mugukora PCB zikomeye. Intambwe zikurikira zirimo tekinike nyinshi.

Bifata igihe kingana iki kugirango ubyare PCB ikomeye?
Ibikurikira nigihe gikenewe cyo kubyara PCB zikomeye muri Richfulljoy.
Bifata iminsi 1-5 kugirango byihuse PCBs.
Ibyumweru 1-2 bifatwa kuri prototype hamwe nuruhererekane ruto rwo gukora PCB zikomeye.
Ibyumweru 2-4 bimara umusaruro mwinshi wa PCB zikomeye.
Ni irihe tandukaniro nyamukuru: Rigid PCB vs flex PCB?
Itandukaniro nyamukuru hagati yubuyobozi bukomeye bwa PCB nubuyobozi bwa flex PCB ni:
1), Byakozwe nibikoresho bitandukanye: imbaho zumuzunguruko zikomeye zikorwa na FR4, ceramic, icyuma cyuma, PTFE nibindi, byose birakomeye (ntibishobora kugororwa), mugihe PCB yoroheje ikorwa na polyimide (PI), PET , Kapton matrial ishobora kugororwa inshuro ibihumbi;
2), Niba byunamye cyangwa bidahinduka: PCB igoye ntishobora kugororwa, ariko flex PCB irashobora kugororwa;
3), Bafite imikoreshereze itandukanye: imbaho zumuzunguruko zikomeye zikoreshwa mubikoresho bya elegitoronike bitimuka, ariko imbaho zumuzunguruko zikoreshwa mubikoresho bihora byimuka, nka kamera, mudasobwa zigendanwa, terefone zigendanwa, iperereza ryimuka nibindi.
Bisaba angahe kubyara PCB ikomeye?
